A licati fil d March 10,1904. Serial No. 197,445. (No model.)

1'0 (n71 whom it mwy concern:

Be it known that 1, S'rnrrmx P. LAPHAM, a citizen of the United States,residing at Pike, in the county of \Yyoming and State of New York, haveinvented a new and useful Combined Screw Driver and Holder, of which thefollowing is a specification.

My invention relates to screw-drivers, and has for its objects toproduce a comparatively simple inexpensive device of this characterhaving means forengaging and securely holding a screw while beingoperated upon and to provide for locking said means in engagingposition.

To these ends the invention comprises the novel features of constructionand combination of partsmore fully hereinafterdescribed.

In the accompanying drawings, Figure 1 is a side elevation of myimproved device. Fig. 2 is a longitudinal sectional elevation. Fig. 3 isa side elevation showing the driver projected beyond the clamping-jaws.Fig. i is a detail section on the line a a of Fig. 1.

Referring to the drawings, 1 designates the screwdriver handle, providedwith a cylindrical portion or shank 2, having a central longitudinalopening or socket 3, designed to receive the inner end of thescrew-driver shank 4, of which it forms, in effect, a continuation. Theouter end of the shank at is flattened or otherwise formed, as at 5, forengagement with a screw, while the inner end of the shank 4, whichenters the socket 3, is preferably of semicircular form in cross-sectionand has its flattened side engaged by the correspondingly-flattenedportion of a pin 6, extended transversely through the handleshank 2,whereby the parts are detachably connected and held against relativerotation.

Surrounding the cylindrical portion or shank 2 and slidablelongitudinally thereon is a tubular sleeve 7, provided at its forwardend with a reduced tubular portion 8, adapted to surround the shank atof the screw-driver, the portion 8 being surrounded adjacent to itslongitudinal center by a fixed collar 9, forward of which said tube issplit to produce a pair of oppositely-disposed spring-jaws 10,constituting screw engaging and holding members or devices. The jaws 10,which are suitl ably and reversely bent adjacent to their outer orforward ends to produce a screw-head receiving space or socket 11, areprovided in rear of said socket with a pair of cooperating fingers orelements 12, carried, respectively, by the jaws and in advance of thesocket, with a pair of inwardly-extending cooperating screw-engagingportions 13 oppositely recessed to conjointly embrace the shank of ascrew, the finger 12 of one jaw being extended transversely beyond thatof the other, whereby the adjacent end of the driver in moving toengaging position as hereinafter explained will pass between them andserve to draw the jaws together for securely holding the screw.

Provided on the sleeve 7 is a suitable enlargement 15, through which aclampingscrew 16 is tapped with its inner end projecting into alongitudinal slot or seat 17, formed in the shank portion 2. The screw16, which acts in conjunction with the ends of the slot 17 as anabutment for limiting the longitudinal movement of the sleeve upon theshank, may be manipulated for locking said parts against relativemovement and, further, serves as a knob or projection for engagement bythe operator in sliding the sleeve back and forth upon the shank 2,whereby the screw performs the threefold function of a stop member, aclamping or locking member, and an operating member for the sleeve.

In practice when it is desired to hold a screw for inserting the samethe screw is manipulated to release the sleeve, which latter is thenmoved forward on the shank, thereby withdrawing the end 5 of the driverfrom between the screw-engaging portions of the jaws 10. The screw isthen inserted between said jaws, and the sleeve is moved rearward on theshank, this action serving to project the driver forwardly between thelingers 12, thereby drawing the jaws together and causing the engagingportions 13 to snugly embrace the shank of the screw. After the end ofthe driver has been properly seated in the screw-head slot, the clamping member or screw 16 may be manipulated for locking the sleeveagainst further movement on the shank, thereby securely holding thescrew while being operated upon.

To remove a screw,'the

engaging end of the driver is projected beyond the engaging portions 13of the jaws by moving the sleeve to its extreme rearward position uponthe shank 2. After the screw has been sufliciently loosened the jawsmay, if so desired, be engaged therewith in the manner just explained.

From the foregoing it is apparent that I produce a simple device whichwill admirably perform its functions; but it is to be understood that Ido not limit myself to the precise details herein set forth, inasmuch asminor changes may be made Without departing from the spirit of theinvention.

Having thus described the invention, what is claimed is 1. Thecombination with a screw-driver, of a pair of screw-engaging memberscarried thereby, said driver being adapted for longitudinal movementrelative to the members, a pair of cooperating elements providedrespectively on the members for engagement with the driver to move themembers to screwretaining position, and means for locking the driveragainst movement.

2. The combination with a screw-driver having a shank, of a sleeveslidable longitudinally of the shank, a pair of screw-engaging memberscarried by the sleeve for longitudinal movement relative to the driver,means controlled by the movement of the latter for moving the members toscrew-retaining position, and means for locking the sleeve againstmovement.

3. The combination with a screw-driver having a shank, of a sleeveslidable longitudinally of the shank, a pair of screw-engaging memberscarried by the sleeve for longitudinal movement relative to the driver,means controlled by the relative movement of the parts for moving themembers to screwretaining position, abutments provided on the shank, anda locking device carried by the sleeve for locking the parts againstrelative movement, said device cooperating with the abutment to limitsaid movement of the parts.

I. The combination with a screw-driver having a shank and a handle, of apair of cooperating screw-engaging members carried by and adapted formovement longitudinally of the shank, means controlled by the relativemovements of the parts for moving the members to screw-retainingposition, and an operating member disposed adjacent to the handle andoperatively connected With the screw-engaging members for actuating thelatter.

5. The combination With a screw driver having a shank and a handle, of apair of STEPHEN P. LAPHAM.
